Embodiment Construction

[0058] An example is given below, and the specific implementation manner of the present invention is further described in detail.

[0059] A steel company has two sets of oxygen generators, which provide low-pressure oxygen and medium-pressure oxygen. The oxygen required by the workshop is supplied by the whole plant pipe network. Flow, pressure, temperature measuring devices and filters are installed on each delivery pipeline at the entrance of the workshop. And cutting device, etc., and then sent to each user for use.

[0060] The average oxygen consumption of users in a certain period of time

[0061]

[0062] First, set the oxygen production volume y of the oxygen generator in the current period 1 =75000,y 1 =63750. When the current gas storage capacity of the oxygen spherical tank is vector 03 , △Q j = 0; when the stored oxygen in the spherical tank is higher than the maximum safe range, ΔQ j =-2000; when the stored oxygen amount of the spherical tank is lower t...

Abstract

The invention relates to a method for optimizing distribution of an oxygen production system of an iron and steel enterprise, belonging to the technical field of oxygen system dispatching. At the first stage, the equation establish cites the control amount to reduce or increase the pressure to the prescribe range, and to take account of the user's release. In the second stage, according to the demand characteristics of different users, the aerobic users are divided into a stable user and a fluctuating user, the overall pressure constraint is determined, and a constraint equation is established. The global optimal solution or the bounds of the optimal solution of the assignment problem can be obtained by solving the model. The algorithm can provide the best solution to the oxygen distribution problem by using the optimal solution to plan the distribution scheme. The utility model has the advantages that the efficiency of directly distributing the oxygen to the user is high, and the oxygen utilization rate is improved and the energy is saved when the oxygen pipe network pressure in the oxygen dispatching process is within the prescribed range.

Description

technical field [0001] The invention belongs to the technical field of oxygen system dispatching, and in particular provides a method for optimizing the distribution of an iron and steel enterprise's oxygen production system, which fully utilizes the oxygen produced by an oxygen generator, thereby improving the utilization rate of oxygen. Background technique [0002] Iron and steel enterprises are industries with high energy consumption, high pollution and high emissions. Oxygen system is an indispensable energy equipment in the smelting process. The use of large amounts of oxygen by enterprises also brings about unreasonable consumption. In the optimal distribution of the oxygen system, it is necessary to consider not only the energy saving of individual equipment but also the energy saving of the overall system, so as to save energy and improve efficiency. Due to the increasing size of steel enterprises, the demand for oxygen is increasing rapidly. The oxygen consumption...
